Math professor: Here's why no one has found a trace of missing Flight MH370
A Texas A&M University professor and his team in Qatar have a mathematical theory about why search crews have found no trace of Malaysia Airlines Flight 370 more than a year after it went missing.
Dr. Goong Chen, whose research on this theory was published in the American Mathematical Society's journal, argues that the plane could have nosedived into the Indian Ocean at a 90-degree angle and remained somewhat intact as it sank to the bottom.
At 1:30 a.m. on March 8, the plane carrying 239 people dropped off air-traffic-control screens less than an hour into a flight from Kuala Lumpur to Beijing.
One of the biggest mysteries surrounding Flight MH370 is the fact that, despite experts tracking the plane's satellite pings to the southern Indian Ocean, searchers have never found a debris field or oil slicks from the supposed crash.
Texas A&M noted that in the case of Air France Flight 447, crews recovered thousands of pieces of floating debris from the Atlantic Ocean just days after the plane crashed in 2009.
In this situation, there would likely be a field of floating debris on the surface of the water.
But a vertical entry would be much smoother, with a smaller "bending moment." The plane's wings would have likely broken off immediately, but since they're heavy, they probably would have sunk to the bottom of the ocean.
So if the plane nosedived into the ocean, it could have sunk somewhat intact and landed belly-up on the ocean floor, according to the research paper.
The ocean's current would have guided the plane to its resting place at the bottom. Lightweight debris like seat cushions and passenger belongings probably wouldn't be able to float to the ocean's surface if the plane's body sank intact.
The plane's stalling from a steep climb, the aircraft's mechanisms malfunctioning, and the plane's running out of fuel could have caused MH370 to plunge into the ocean at a sharp angle, according to the research paper.
Chen and his team created simulations of what the descent might have looked like:
The plane entering the water at this angle wouldn't have created the same large waves as an entry at a lesser angle. Big waves would have likely caused more break-up of the plane at the surface.
The animation below shows the supposed distribution of pressure. The paper notes that aviation experts say that how a plane enters the water determines how it breaks up.
In other scenarios Chen and his team looked at, the plane's angle of entry would have created bigger waves and more pressure, which likely would have caused the plane to break up more near the water's surface.
The disappearance of MH 370 is one of the most bizarre and tragic aviation mysteries of all time. Investigators have not offered any conclusive explanation about what happened to the plane after it disappeared from radar.
Australian officials announced last month that teams are expanding the MH370 search area in the Indian Ocean. They said that if the plane isn't found there, they're not sure where else to look.
